月球卫星轨道力学综述

月球探测器的运动通常可分为3个阶段，这3个阶段分别对应3种不同类型的轨道：近地停泊轨道、向月飞行的过渡轨道与环月飞行的月球卫星轨道。近地停泊轨道实为一种地球卫星轨道；过渡轨道则涉及不同的过渡方式(大推力或小推力等)；环月飞行的月球卫星轨道则与地球卫星轨道有很多不同之处，它决不是地球卫星轨道的简单克隆。针对这一点，全面阐述月球卫星的轨道力学问题，特别是环月飞行中的一些热点问题，如轨道摄动解的构造、近月点高度的下降及其涉及的卫星轨道寿命、各种特殊卫星(如太阳同步卫星和冻结轨道卫星等)的轨道特征、月球卫星定轨等。

On the Orbit Dynamics of Lunar Satellite

The motion of lunar probe consists of three stages including three different type of orbits: parking orbit near the Earth, transfer orbit forward to the Moon and the final orbit around the Moon. The parking orbit is a certain kind of orbit of the Earth satellite. The transfer orbit differs from the others in transfer method (such as impulse and low thrust). The final orbit around the Moon is not the clone of the Earth satellites' orbit though they are similar in some aspects. In this paper, we talk about the orbit mechanics of lunar satellites widely and focus on some hotspots, for instance, the construction of the perturbation solution, orbital lifetime, special satellites as sun-synchronous and frozen orbits and the precise orbit determination.
